[335 oClock]

Im with the jb4 stage2 for a couple of months and recently a few days ago added BMS downpipe
a few days ago got an error half engine light saying engine power is reduced ... got real worried, shut the car off for a few mins turned it on and its been fine since then

I spoke with somebody and they said that will happen but dont worry your modded and this is what you have to put up with, but the car is fine

I was wondering if anybody with a different downpipe with the jbstage 2 tune has had this issue, or what your response would be to this?
